Application Pool in IIS automatically stopped RRS feed

  • Question

  • I have a application in which worker process recycle is scheduled on 3 AM every day.

    Randomly on same time (3 AM) application pool is automatically stopped.

    After checking in event logs 2 warning messages were found 

    1)a process serving application pool exceeded time limits during shut down

    2)A worker process 'XXXX' serving application pool  failed to stop a listener channel for protocol 'http' in the allotted time.  

      This case start occurring after i upgrade my environment from .NET framework 4.0 to .NET framework 4.6.2 .

  • Hi Zafeer.Khawaja,
    Based on your description, I have some suggestions you can refer to.
    1.You can stop and restart the application pool by following the steps:
    1.1 Open the Control Panel> System and Security> Administrative Tools.
    1.2 Right-click Internet Information Services (IIS) Manager and select Run as administrator.
    1.3 In the Connections pane, expand the server node and click Application Pools.
    1.4 On the Application Pools page, select the application pool you want to stop and start.
    1.5 In the Actions pane, do one of the following:
    1.6 Click Stop to stop the application pool.
    1.7 Click Start to start the application pool.
    More details you can refer to this document.
    2.You can change Ping Enabled to false and check if that fixes the issue.
    Plesae following the steps below:
    2.Go into IIS, click Application Pools. Then right-click on your app pool and choose Advanced Settings. Under the Process Model heading, set the value of Ping Enabled to false. 
    3.Another option is to increase the Ping Maximum Response Time.
    Here is a related document you can refer to.
    Best Regards,

    You should post to the IIS forums for help.
